     簡 介Introduction
　　SF6氣體單向閥主要用于SF6氣體壓力（密度）表與設(shè)備之間的過渡裝配。可以使設(shè)備在充壓下能夠更換儀表或進(jìn)行鑒定及其保養(yǎng)維護(hù)。
SF6 gas check valves are used as an interim fitting between SF6 gas special pressure （density） gauge and the equipment.It enables replacement or verification or maintenance of the instrument while the equipment is filled with the gas.

      本產(chǎn)品的特點(diǎn)是使用方便，氣密性能可靠也可用于其它類似的場所，但必須是非腐蝕性介質(zhì)相配套的壓力表系統(tǒng)。

      This instrument features easy utility, reliable sealability, and can be used in similar application where corrosive media doesnot exist. When using, fasten the hex nut to open the valve,
   　使用單向閥時，將連接接頭上的六方螺母懸緊，閥芯將被打開SF6 氣體將通過單向閥進(jìn)入儀表，進(jìn)行壓力輕度控制，使用完畢懸松六方螺母氣路將被切斷。

       SF6 gas enters the instrument via the valve, pressure is controlled slightly. After using, loosen the hex nut to cut off the gas.

      備注：本公司也可根據(jù)情況滿足客戶的特殊需要！

      Note: we can also built to customer’s need.
